Evidence for Global Warming: Is Global Warming Real?

Global warming is real, and it is caused by humans. How can I say this?

The evidence is overwhelming.

Global temperature records, kept by a variety of scientific organizations, show rising temperatures over the past 150 years. Snow cover across the northern hemisphere has declined over the past decades. Spring is coming earlier each year. The sea ice at the north pole is melting even faster than the climate models predict. The south pole also appears to be losing ice – again, faster than predicted.

Glaciers are melting all over the world, and animals are changing their behavior.

There are multiple streams of evidence pointing to greenhouse gases like CO2 as the cause of the current warming.

Global warming is real.
